7 Claims.

This invention relates to an oscillatory drive for siiver receiving cans used in connection with cotton drawing machines.

The object of the invention is to provide, in

5 a manner as hereinafter set forth, a drive for the purpose referred acting to reversely revolve the can, at each complete revolution of the latter to overcome the slight twist or turn ordinarily put on the coils during drawing of the sliver,

10 thereby resulting in the affording of ease and expedition in the uncoiling of the sliver when spinning.

The invention has for its further object to provide, in a manner as hereinafter set forth, a drive 16 of the class referred to which is simple in its con struction andarrangement, strong, durable, compact, readily installed with respect to a cotton drawing machine and a sliver receiving can associated with such machine, thoroughly efficient 20 in its use, conveniently assembled and comparatively' inexpensive to manufacture.

Embodying the objects aforesaid, and to others which may hereinafter appear, the invention consists of such parts and such combinations of parts 25 as will be more specifically referred to and as illustrated in the accompanying drawings, whereini's shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

'With reference to Figure l of the drawings 50 there is shown an apertured coiler plate I, a peripherally toothed revoluble coiler 2 in the aperture of and slidably coupled to plate I, a driving means 3 for coiler connected to and arranged over the plate I, and an operating means 4 for the driving means'3 arranged over plate I and meshing with the means 3. The plate I, coiler}; driving means 3 and operating means 4 arej'eleinents'which correspond in form. to like elements of cotton drawing machines now in gene'ral'use. There is associated with and arranged below the coiler 2 a driven revoluble open top can 5 for receiving'the sliver from the coiler. I'he latter revolves at a greater speed than the can. The foregoing elements are of known construction and are illustrated for the purpose of 10 showing the drive, in accordance with this invention installed with respect to the machine and can.

The oscillatory drive, in accordance with this invention for the can 5 acts to reverse the direction of movement of the latter after each substantially complete revolution of the can to obtain the object as aforesaid when coiling the sliver. "The drive includes a power transmission which takes off from the driven shaft 6 of the operating means 4 for the coiler 2. The power take-off transmission includes a bevel pinion I fixed to shaft 6, a bevel pinion 8 meshing with the driven'pinion I and a vertically disposed shaft 9 extending through and depending from the platformor the plate I adjacent the coiler 2. The shaft9 lengthwise of its periphery is formed with a groove It, and is also formed at its lower end with an adjustable stop collar II.

The drive includes'a combined carrying and revolving mechanism I2 for the can 5. The mechanism 'l2includes a vertically disposed rotatable shaft 'I3, a gear train I4 consisting of a pair of horizontally disposed spaced aligned gears I5, I'B ofi'different diameters and an intermediate gear I'I. ofiless diameter than, aligning with, arranged between" and meshing with the gears I5, IS, an upstanding revoluble shaft I8 fixed to gear I5, and arevoluble flanged carrier element It fixed tothe upper end of shaft I8. The bottom portion of can 5, is fixed in the element I9, the latter bodily'revolves the can therewith. The gear I1 is revoluble' about a hanger shaft 20. The gear I5v and the'major portion of gear Il are arranged in a closed top and open bottom housing 21. The shaft I8" extends upwardly through, the shaft 20 depends from and bearings 22 depend from the top of housing 2I for shafts I8, 20. Retaining collars 23 are secured to the lower ends of shafts 3,26; A spacer 24 is interposed between element I9 and housing II. The latter at one'side is open fo'r'the passage of a part of the gear II. The gear 16 is' fixed to the lower end of shaft I3. The latter isarranged within and axially 'of an upstanding closed top and bottom cylindrical cas- 'with and drives the gear 5| ing 25 disposed in horizontal aligned spaced relation with respect to can 5. The top 25 and the bottom 27 of the-casing 25 have secured to their inner faces oppositely disposed bearings 28, 29 respectively in which the ends of shaft |3 are positioned. The casing 25, at one side is formed with a cut-out 36 for the passage of gear I! to mesh with the gear l6. The latter is of less diameter than the gear I5.

The drive includes a reversible driving mechanism 3| for the combined carrying and revolving mechanism l2 for the can 5. The mechanism 3| consists of a split annular mangle rack 32 having oppositely rounded ends 33, 34. The rack 32 includes an upper 'set 35 and a lower set 36 of beveled continuous teeth. The sets 35, 36 extend from one end to the other of the rack 32 and merge into the teeth 31 formed on the rounded ends 33, 34 of the rack. The teeth 31 are beveled and form continuations of the teeth of the sets 35, 36. The rack 32 is arranged within the casing 25 between the transverse median of the latter and its upper end. The rack 32 is suspended from a combined guide and retainer structure 38 positioned within casing 25, disposed inwardly of, above and below the rack 32 in spaced relation to the latter. The structure 38 includes an upper combined guide and retainer portion 39 in the form of a split annulus, a lower combined guider and retainer portion 49 in the form of a split annulus and a pair of oppositely disposed curved upstanding vertically disposed combined guides, retainers and coupler portions 4|, 42. The portions 39, 48 at one end merge into the ends of the portion 4|. The portion 39, 48 at the other end merge into the ends of the portion 42. The portions 39, 40 are spaced inwardly with respect to the sets of teeth 35, 36 respectively. The portions 4|, 42 are spaced inwardly with respect to the teeth on the rounded ends 33, 34 respectively. The rack 32 is connected to the structure 38 by radially disposed spaced couplers 43 which are integral with the inner face of rack 32 and the outer side surfaces of upstanding outwardly opening spaced curved yokes 44 having their ends integral with the inner side faces of the portions 39, 40 of structure 38. The latter is fixed to the shaft I3, for the purpose of rotating the latter when mechanism 3| is active, by a spider 45 fixed at its center to shaft |3 and at its outer ends to the inner side faces of the yokes 44. The structure 38 and shaft l3 bodily rotate in unison, and for such purpose a rotatable beveled pinion 46 is provided for successively travelling over and engaging with the upper and lower sets of teeth 35, 36 and also for successively travelling over and engaging with the teeth 31 at the ends 33, 34 of the rack. The pinion 46 is carried by a rotatable shaft 48 which is extended inwardly from said pinion. That portion of shaft 48 extended inwardly from pinion 46 carries a combined guide and retainer roller 49. The shaft 48 is extended outwardly from pinion 46 and is journaled in a vertically movable bearing 50 slidably mounted on shaft 9. Fixed to shaft 48, inwardly adjacent to bearing 50 is a bevel gear 5|. Keyed to the shaft 9 and slidably mounted on the latter, above the bearing 56 is the hub 52 of a bevel-gear 53 which meshes Slidably mounted on shaft 9, above the hub 52 is a collar 54, which is connected to the bearing 58, by a laterally extended coupling arm 55. The hub 52 bodily rotates with shaft 9, but is vertically slidable relatively to the latter, and for such purpose, a connecting screw or key 56 is carried by the hub 52 and has its inner end terminal portion plain and slidably mounted in the groove l8.

When the pinion 46 is travelling across and engaging with the upper set of teeth 35 of the rack 32, the latter is driven in a clockwise direction carrying shaft |3 therewith in a like direction. When the pinion 46 is travelling across and engaging with the lower set of teeth 34 of the rack 32, the latter is driven in an anticlockwise direction carrying shaft |3 in a like direction. The pinion 46, when coacting with the upper set of teeth 35 is held in engagement with the latter by the roller 49 travelling against the lower face of the portion 39 of structure 38. The pinion 46, when coacting with the lower set of teeth 36 is held in engagement with the latter by the roller 46 travelling against the upper face of portion 40 of structure 38. It will be assumed with reference to Figure 4, that the pinion 46 is coacting with the upper set of teeth 35 and rack 32 is moving in a clockwise direction, and when rack 32 completes substantially a clockwise revolution, the end 33 of the rack will have reached the pinion 46, the latter will then travel downwardly of the teeth 3'! on end 33 of rack 32, engage the lower set of teeth 36 and impart to the rack 32 an anti-clockwise movement. When rack,

32 completes substantially an anti-clockwise revolution, the end 33 of the rack will have reached the pinion 46, the latter will then travel upwardly of the teeth 37 on the end 34 of the rack, en-

gage the upper set of teeth 35 and impart to The pulley 46 rack 32 a clockwise movement. as it travels downwardly and upwardly will carry the roller 46, shaft 48, gear 5|, bearing 50 and hub 52 therewith but with the gears 5|, 52 retained in mesh on the downward or upward travel of pinion 46. Owing to the manner in which the gears |5, |6 and I! are arranged the can 5 will be revolved at all times in a direction corresponding to the direction in which the rack 32 is revolved.

The cylinder 25 is formed with a vertical elongated slot 51 to provide a clearance for the vertical movement of the shaft 48.

The pinion 46, shaft 48, roller 49, bearing 58, gear 5|, bearing 52, gear 53, collar 54 and arm 55 coact to provide a slidably suspended driven means automatically bodily movable in alternatedirections in a rectilinear path. The suspension and driving means for said driven means is pro vided by the shaft 9.
